The utility model aims at solving the problem of relatively poor waterproof performance of the vent valve in the prior art and providing a waterproof vent valve.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

waterproof ventilation valve, including the cap body, the lower extreme fixedly connected with installation body of the cap body, be equipped with ventilative groove jointly between installation body and the cap body, the internal waterproof chamber that is equipped with of cap, it is a plurality of waterproof chamber all is linked together through interconnection through-hole and ventilative groove, and is a plurality of waterproof chamber is linked together through intercommunicating pore and outside, and is a plurality of all sealed sliding connection has waterproof in the waterproof chamber.

Preferably, the cap body is in the regular polygon setting, the quantity of waterproof chamber matches with the limit number of cap body, a plurality of waterproof chamber evenly arrayed distributes in the cap body.

Preferably, the waterproof cavity and the waterproof piece are both arranged in a polygon similar to the cap body.

Preferably, the diagonal length of the flashing is slightly less than the diagonal length of the chamber.

Preferably, when the inner connecting hole and the outer communicating hole are located at horizontal positions, the highest point of the horizontal position of the waterproof member is higher than the horizontal positions of the inner connecting hole and the outer communicating hole.

Preferably, the mounting body is cylindrical, and the outer wall of the mounting body is provided with threads.

Preferably, the installation body is externally sleeved with an annular cushion and a threaded ring, and the installation body is in threaded connection with the threaded ring.

Preferably, a plurality of the outer communication holes are all provided with dust screens.

Compared with the prior art, the beneficial effects of the utility model are that:

by arranging the waterproof cavity and the waterproof part, when the heat in the lamp is high, the air is heated and expanded, at the moment, the hot air is discharged through the plurality of inner connecting holes and the outer connecting holes, and the cold air enters, the lamp can be radiated, when the vent valve is used, the waterproof piece in the waterproof cavity is in sealing and abutting contact with the inner wall of the lower side of the waterproof cavity under the action of gravity, when rainwater falls from the upper side, the rainwater can only enter the outer communicating hole of the upper side, the inner waterproof part seals the inner through hole, thereby achieving the waterproof effect, rainwater entering from the side surface, because the highest level of the outer communication hole is lower than that of the inner waterproof piece, rainwater can not enter the inner communication hole beyond the waterproof piece, therefore, a good waterproof effect is achieved, and meanwhile, the plurality of inner connecting through holes and the plurality of outer connecting through holes which are located on the two sides are communicated through the waterproof cavities, so that the lamp is good in air permeability.

The utility model discloses the waterproof effect is better and the gas permeability is good.

In the figure: the novel waterproof cap comprises a cap body 1, a mounting body 2, a ventilation groove 3, a waterproof cavity 4, an internal through hole 5, an external through hole 6, a waterproof piece 7, an annular cushion 8 and a threaded ring 9.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-5, the waterproof vent valve comprises a cap body 1, wherein the lower end of the cap body 1 is fixedly connected with an installation body 2, a vent groove 3 is jointly arranged between the installation body 2 and the cap body 1, a plurality of waterproof cavities 4 are arranged in the cap body 1, the waterproof cavities 4 are communicated with the vent groove 3 through interconnection through holes 5, the waterproof cavities 4 are communicated with the outside through outer communication holes 6, it is noted that when the interconnection through holes 5 and the outer communication holes 6 are positioned at horizontal positions, the highest point of the horizontal positions of the waterproof parts 7 is higher than the horizontal positions of the interconnection through holes 5 and the outer communication holes 6, the waterproof parts 7 are hermetically and slidably connected in the waterproof cavities 4, the cap body 1 is in a regular polygon shape, the number of the waterproof cavities 4 is matched with the number of the sides of the cap body 1, the number of the sides of the cap body 1 is more than or equal to six, and the waterproof cavities 4 are uniformly distributed in the cap body 1 in an array manner, it is worth mentioning that waterproof chamber 4 all is the polygon setting similar with the cap body 1 with waterproof 7, need explain that, the installation body 2 is cylindrical setting, and the outer wall of the installation body 2 is equipped with the screw thread, and it is worth mentioning that, 2 overcoat of the installation body is equipped with annular cushion 8 and screw ring 9, threaded connection between the installation body 2 and the screw ring 9, and it is worth mentioning that, all installs the dust screen in a plurality of outer intercommunicating pores 6.

When the utility model is used, when the heat in the lamp is high, the air is heated to expand, at the moment, the hot air is discharged through the inner connecting holes 5 and the outer connecting holes 4, the cold air enters, the lamp can be cooled, when the vent valve is used, the waterproof part 7 in the waterproof cavity 4 is in contact with the inner wall at the lower side of the waterproof cavity 4 in a sealing and propping way under the action of gravity, when the rainwater drops from the upper side, the rainwater can only enter the outer connecting hole 6 at the upper side, the inner waterproof part 7 seals the inner connecting holes 5, thereby achieving the waterproof effect, the rainwater entering from the side surface can not cross the waterproof part 7 to enter the inner connecting holes 5 because the highest horizontal plane of the outer connecting holes 6 is lower than the highest horizontal plane of the inner waterproof part 7, thereby achieving the waterproof effect, meanwhile, the inner connecting holes 5 and the outer connecting holes 6 at the two sides are communicated through the waterproof cavity 4, so that the lamp has good air permeability.
